The MAFS heat wave: Relive the sexiest moments we've seen so far

From Michael and Martha on the beach to Jules and Cam going all the way.

As our couples continue in the experiment, they inevitably are becoming closer with each other (we're aware of a few exceptions). But from Mike and Heidi's instant sexual chemistry, to other couples' sneaky pool pashes, there have been a lot of moments that simply make your heart race.
